Description

Technical Field

[0001] This utility model relates to the field of sanding machine technology, specifically a sanding machine for double-sided wood board processing. Background Technology

[0002] Sanding refers to the physical removal of unevenness, inconsistent thickness, or non-compliant materials and objects using tools such as sandpaper, sanding wheels, abrasive cloths, scouring pads, and non-woven polishing wheels to make them smoother, flatter, and more uniform in thickness. Sanding machines can be used to process the surface of wood boards, making them smoother.

[0003] When processing double-sided wood panels, a sander is needed to polish both sides of the panel to make it smoother. However, existing sanders can only rotate the sanding wheel in a fixed position to polish the wood panel. The polishing method is relatively simple and it is difficult to polish the wood panel evenly. Utility Model Content

[0009] Preferably, a servo motor b is installed on the side of the machine body near the servo motor a, the output end of the servo motor b is fixedly connected to the grinding roller a, and a connecting frame a is movably connected to the outer side of the threaded sleeve through a bearing.

[0010] Preferably, one side of the connecting frame a is fixed to the conveyor, one end of the threaded sleeve is fixedly connected to the synchronous pulley b, the outer side of the synchronous pulley b is fitted with a synchronous belt, and one side of the synchronous belt is fitted with the synchronous pulley a.

[0013] Compared with existing technologies, the advantages of this double-sided wood board sanding machine are as follows: When sanding wood boards, the double-sided wood board sanding machine drives the sanding rollers b and a to rotate by starting servo motors a and b. Then, the drive motor starts the reciprocating motion mechanism, which drives the connecting plate to rotate. The connecting plate slides in the groove inside the fixed plate through the protrusion on its top, thereby moving the fixed plate and the machine body on top of it back and forth. The machine body can also drive the rotating sanding rollers b and a to reciprocate, thus uniformly sanding the wood boards. In this way, the wood boards in the sanding machine can be uniformly sanded through the above operation. Attached Figure Description

[0021] Please see Figures 1-5 This utility model provides a technical solution: a double-sided wood board sanding machine, comprising: a machine body 1 and a limiting mechanism 6, wherein a sanding roller a2 and a sanding roller b3 are arranged inside the machine body 1, and conveyors 4 are arranged on both sides of the machine body 1, and a conveyor belt 5 is installed on the top of the conveyor 4.

[0022] A limiting mechanism 6 is provided at the top of the conveyor belt 5. The limiting mechanism 6 includes a slide rod 609 that is slidably connected to the inside of the conveyor 4. A connecting plate 608 is fixedly connected to one end of the slide rod 609. A threaded rod a607 is movably connected to the middle of the connecting plate 608 through a bearing. A threaded sleeve 605 is threadedly connected to the outside of the threaded rod a607. Multiple sets of limiting wheels 610 are movably connected to one side of the connecting plate 608 through a rotating shaft. A reciprocating motion mechanism 7 is provided at the bottom of the machine body 1. The reciprocating motion mechanism 7 includes a fixed plate 706 that is fixedly connected to the bottom of the machine body 1. A protrusion 705 is slidably connected inside the fixed plate 706. A connecting disc 704 is movably connected to the bottom of the protrusion 705 through a rotating shaft.

[0023] A threaded rod b9 is threaded to the top of the machine body 1. A connecting frame b8 is movably connected to the bottom of the threaded rod b9 via a bearing. A grinding roller b3 is movably connected to the inner side of the connecting frame b8 via a bearing. One end of the grinding roller b3 is fixedly connected to the output shaft of the servo motor a11. One side of the servo motor a11 is fixed to the connecting frame b8. A limit rod 10 is fixedly connected to the top of the connecting frame b8, and the outer side of the limit rod 10 is slidably connected to the machine body 1. A servo motor b12 is installed on the side of the machine body 1 near the servo motor a11. The output end of the servo motor b12 is fixedly connected to the grinding roller a2. A connecting frame a606 is movably connected to the outer side of the threaded sleeve 605 via a bearing. One side of the connecting frame a606 is fixed to the conveyor 4. A synchronous pulley b60 is fixedly connected to one end of the threaded sleeve 605. 4. A timing belt 603 is sleeved on the outer side of the timing pulley b604, and a timing pulley a602 is sleeved on one side of the timing belt 603; a connecting shaft 601 is fixedly connected to one side of the timing pulley a602, and the outer side of the connecting shaft 601 is movably connected to the conveyor 4 through a bearing; the threaded sleeve 605 and the threaded rod a607 form a threaded transmission structure; a slider 701 is fixedly connected to the bottom of the machine body 1, and a fixed frame 702 is slidably connected to the outer side of the slider 701; a drive motor 703 is installed inside the fixed frame 702; the top of the drive motor 703 is fixed to the connecting plate 704; a sliding groove matching the slider 701 is opened on the top of the fixed frame 702; the slider 701 and the fixed frame 702 form a sliding structure; a strip groove matching the protrusion 705 is opened inside the fixed plate 706.

[0024] In practical implementation, when the double-sided wood processing sander is sanding the wood, the servo motors a11 and b12 are started to drive the sanding rollers b3 and a2 to rotate. Then, the drive motor 703 is started to make the reciprocating motion mechanism 7 start to move. The drive motor 703 will drive the connecting plate 704 to rotate, and the protrusion 705 on the top of the connecting plate 704 slides in the strip groove inside the fixed plate 706, thereby moving the fixed plate 706 and the machine body 1 on top of it to reciprocate. The machine body 1 can drive the rotating sanding rollers b3 and a2 to reciprocate as well, thereby sanding the wood evenly.

[0025] To keep the wooden board stable during sanding, the connecting shaft 601 is rotated, which drives two sets of synchronous pulleys a602 to rotate. The synchronous pulleys a602 then drive the synchronous pulley b604 to rotate via the synchronous belt 603, which in turn drives the threaded sleeve 605 on one side of the synchronous pulley b604 to rotate, causing it to engage in threaded transmission with the threaded rod a607. This causes the connecting plate 608 at one end of the threaded rod a607 to move. The sliding rod 609 limits the movement of the connecting plate 608. As the connecting plate 608 moves, it drives multiple sets of limiting wheels 610 to move closer to the edge of the wooden board, thus limiting the board. When the thickness of the wooden board changes, the threaded rod b9 can be rotated to engage in threaded transmission with the machine body 1, which in turn drives the bottom connecting frame b8 and the sanding roller b3 to move, thus bringing them close to the top of the wooden board. Through the above operations, the wooden board in the sander can be sanded evenly.

[0026] In summary: When using a double-sided wood sander, first start the servo motors a11 and b12 to drive the sanding rollers b3 and a2 to rotate. Then, place the wood board on the conveyor belt 5 and feed the wood board between the sanding rollers b3 and a2 to sand both sides of the wood board. Any content not described in detail in this instruction is prior art known to those skilled in the art.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
